The pinnacle of all English swearwords, thundercunt is phoenetically, spiritually, grammatically, and socially the worst thing you can ever say. Much like a Holy Hand Grenade or the most powerful zord from Power Rangers, it should only be used in times of extreme need

Man: Larry, your home just burned down, and the arsonist fucked your wife
Larry: THUNDERCUNT!!!!
Universe: Shatters a little bit, shaken to its very core

Any woman fitting the definition of a completly hanous raging bitch, who, upon picturing naked you envision the depths of nothingness encapsulated by the most disgusting hairy herpes infested vagina EVER!

A cunt of the highest order, who finds new and exciting ways of pissing off her significant other. Thundercunts tend to be over 300 lbs, and hate working just as much as they love chicken nuggets from Wendy's.

Jennifer, you fat fucking pig. Stop being a thundercunt and open the door. I have nuggets for you.....

A thunder cunt is when a female has such a large vagina that is slaps against her thigh making a very low frequency sound similar to thunder… it is said that rhinos and elephants can hear it from miles away.
An example of a woman with a thunder cunt would be for instance…
- Rosie O’Donnell
- Monique
- Any woman on the biggest loser

1. a megacunt, usually white trash by nature, who needs to learn when to shut her trap 2. an excessively bitchy person, who spends her days making others feel worthless

At a community service project last Friday a Thundercunt came up to her car and bitched, "Who put a wata bottle on mah car?!?".
That thundercunt Dr Bange failed that group because their memo was not stapled.
